G2: Alternative bioresources and biofuels
In the last years, Alternative Bioresources and Biofuels Team’s (E2) research was focused on 2 important directions: 1. Alternative Bioresources – research activities regarding on use of microalgae for the decontamination of wastewater; the complex use of microalgae for obtaining useful compounds (lipids, antioxidants, biostimulants, phytocatalysts); sustainable biosequestration of GHG in microalgal photosynthetic systems; exploitation of natural resources to obtain food supplements. 2. Biofuels – research activities regarding on the obtaining of third-generation biofuels (aviation biofuels from algal oil) and second-generation biofuels (biodiesel); biogas obtaining; valorisation of by-products from the biodiesel production; ecological solvents from animal or vegetables wastes. Interdisciplinary profile of Alternative Bioresources and Biofuels Team allows to carry out applied research in chemistry field and organic chemistry technologies (non-petrochemical products, organic intermediary, complex biomass refinery), unconventional technologies, ecological technologies and products, chemical and instrumental analysis, technological transfer, consulting, management and execution of national and international research projects.
